That also helps us understand our own Milky Way, which, ironically, is hard to study because of all the dust blocking our view of the really interesting parts, like the Galactic center, and dense star-forming regions 23 April 2008 John Tierney The Astronomy Quiz: Answers https://web.archive.org/web/20080427032256/https://tierneylab.blogs.nytimes.com/2008/04/23/the-astronomy-quiz-answers/ We appear to be moving around the Galactic center (which is host to a super massive black hole) about once every 250 million years. 31 January 2021 w:Abraham Loeb Did a Supermassive Black Hole Influence the Evolution of Life on Earth? https://web.archive.org/web/20210131170158/https://www.scientificamerican.com/article/did-a-supermassive-black-hole-influence-the-evolution-of-life-on-earth/ Even though SgrA* is dim right now, we have clues that it must have experienced episodes of vigorous feeding in the past. This is not a surprise, given that a gas cloud approaching the Galactic center or a star passing within ten times the horizon scale of SgrA* (which translates to roughly the Earth-Sun separation), would get spaghettified by the strong gravitational tide there and turn into a stream of gas that triggers a quasar-like flare.
